Answer:
n = 18
Step-by-step explanation:
Hi there!

Isolate <em>n</em> by multiplying both sides by 30:

Simplify the fraction:

I hope this helps!
Z = 79° (supplementary to 109°) and y = 102° (all angles of a quadrilateral add to 360, so do 360-96-83-79 to get 102°)
Answer:
4%
Step-by-step explanation:
Volume of sphere
v = (4/3)πr^3
Volume moon/ volume planet
We don't actually need the numeric value of the radius
just the 35% ratio
Radius of moon = .35 radius of planet
Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3
Cancel like terms
Vm / Vp = .35^3
Vm / Vp = 0.042875
Expressed as a percentage
Vm / Vp = 4.2875%
Rounded
Vm / Vp = 4%
The total volume of the three cylinders is given by:
V = (3) * (pi) * (r ^ 2) * (d)
Where,
r: cylinder radius
d: cylinder depth
Substituting values we have:
V = (3) * (3.14) * (4 ^ 2) * (7)
V = 1055.04 feet ^ 3
Answer:
the volume of oil needed is:
V = 1055.04 feet ^ 3
Sqrt(x) - 5+7 =11
combine like terms
-5 +7 = 2
sqrt(x) + 2 = 11
subtract 2 from each side
sqrt(x) = 9
square both sides
x = 9^2
x = 81
an extraneous solution would be an invalid solution
in this case it is not an extraneous solution
